Answer:

\displaystyle \rm  A_{ \text{c  - pentagon}} =41

\rm \displaystyle P _{ \rm c - pentagon} =  20+ 4 \sqrt{2}

Step-by-step explanation:

we have a square and a triangle

we want to figure out the area and the perimeter of the pentagon

to figure out the area of the pentagon we can use the given formula:

\displaystyle \rm  A_{ \text{c  - pentagon}} = A_{ \text{squre}} - A_{ \text{triangle}}

let's figure out A_{\rm square}:

since the given shape is a square Every angle of its 90° Thus the triangle is a right angle triangle

therefore the height is 4

\displaystyle A _{ \rm triangle} =  \frac{1}{2}  \times b \times h

substitute h and b

\displaystyle A _{ \rm triangle} =  \frac{1}{2}  \times 4 \times 4

reduce fraction:

\displaystyle A _{ \rm triangle} =   2 \times 4

simplify multiplication:

\displaystyle A _{ \rm triangle} =   8

likewise square

\displaystyle A _{ \rm squre} =  {s}^{2}

substitute s:

\displaystyle A _{ \rm squre} =  {7}^{2}

simplify square

\displaystyle A _{ \rm squre} =  49

hence,

\displaystyle \rm  A_{ \text{c - pentagon}} =49- 8

\displaystyle \rm  A_{ \text{c  - pentagon}} =41

to figure out perimeter

let's figure out hypotenuse first

\displaystyle h =  \sqrt{ {4}^{2}   +  {4}^{2} }

\displaystyle h =  \sqrt{ 16  +  16}

\displaystyle h = 4 \sqrt{2}

therefore,

\rm \displaystyle P _{ \rm c - pentagon} = 3 + 3 + 4 \sqrt{2}  + 7 + 7

\rm \displaystyle P _{ \rm c - pentagon} = 6 + 4 \sqrt{2}  + 14

\rm \displaystyle P _{ \rm c - pentagon} =  20+ 4 \sqrt{2}

at the zoom,the ratio of monkeys to gorrillas is 5:2 if there were 20 monkeys how many gorrilas would there be?
Umnica [9.8K]

8 gorrilas

Explanation:

The ratio of monkeys to gorrila = 5:2

This means there are 5 monkeys for every 2 gorrilas

when there are 20 monkeys,

let the number of gorrilas = x

5 monkeys = 2 gorrilas

20 monkeys = x

cross multiply:

5(x) = 20(2)

5x = 40

divide both sides by 5:

5x/5 = 40/5

x = 8

Hence, if there were 20 monkeys, we would have 8 gorrilas.

What is the value of x?<br><br><br><br> Enter your answer in the box.<br><br> x =
melisa1 [442]

The two angles are vertical angles, which means they are the same.

Set the two equations to equal and solve:

2x +2 = 3x -52

Subtract 2x from each side:

2 = x -52

Add 52 to each side:

x = 54

−126 = 14k<br> MAKE SURE TO SHOW YOUR WORK PLEASE HURRY
vovangra [49]

Answer:

k = -9

Step-by-step explanation:

When a number (coefficient) is next to a letter (variable) that means you multiply. To solve you would to the opposite, which is to divide.

-126 ÷ 14 = -9

So -9 is equal to k.

Hope that helps and have a great day!
